A physical therapist assistant collects data on a patient's sharp-dull sensation.
Two days later, the assistant retests the patient's sharp-dull sensation. Which
of the following terms BEST describes the reliability of these measurements?
1. Parallel forms reliability
2. Internal consistency reliability
3. Interrater reliability
4. Intrarater reliability Right Ans - 4. Intrarater reliability
The scenario does not demonstrate interrater reliability, because the same
clinician is doing the measurements, rather than different individuals.
4. This scenario demonstrates intrarater reliability, because the same
individual is using the same measurement tool.
Urge incontinence is BEST characterized by which of the following
descriptions?
1. Loss of urine that coincides with increases in intraabdominal pressure
2. Unexpected and uncontrolled loss of urine
3. Constant leaking of urine from an overdistended bladder
4. Difficulty reaching a toilet in time due to joint or muscle dysfunction
Right Ans - 2. Unexpected and uncontrolled loss of urine
1. Stress incontinence, not urge incontinence, is best characterized by loss of
urine during activities that increase intraabdominal pressure.
2. Urge incontinence is the sudden unexpected urge to urinate and the
uncontrolled loss of urine.
3. Overflow incontinence, not urge incontinence, is the constant leaking of
urine from a bladder that is full but unable to empty.
4. Functional incontinence, not urge incontinence, is best characterized as
difficulty reaching a toilet in time due to joint or muscle dysfunction.
A 16-year-old patient reports developing pain in the shoulders after a 3-year
history of athletic competitions that required repetitive use of the arm in a
movement pattern of lateral (external) rotation and horizontal abduction.
Which of the following impairments is MOST consistent with the patient's
mechanism of injury?
1. Weakness of the deltoid muscle
,2. Anterior glenohumeral joint instability
3. Anterior glenohumeral joint hypomobility
4. Weakness of the latissimus dorsi muscle Right Ans - 2. Anterior
glenohumeral joint instability
2. Anterior instability occurs when the abducted shoulder is repetitively
placed in a position of lateral (external) rotation and horizontal abduction, as
occurs in competitive swimming or various other sports. This can often lead
to recurrent subluxations of the shoulder and ultimately to osteoarthritis or a
torn rotator cuff.
A patient who has an infected Stage 4 medial malleolar pressure injury is
being treated with a comprehensive wound care program. Which of the
following interventions is MOST appropriate?
1. Low-amplitude direct current stimulation with positive polarity
2. High-voltage pulsed current electrical stimulation with positive polarity
3. Low-amplitude direct current stimulation with negative polarity
4. High-voltage pulsed current electrical stimulation with negative polarity
Right Ans - 4. High-voltage pulsed current electrical stimulation with negative
polarity
1. Low-amplitude direct current is used for transdermal drug delivery via
iontophoresis (p. 274). Direct current can cause chemical effects that are
caustic and could damage tissue (p. 231). This would not be appropriate for
wound healing. The positive electrode is most effective to promote healing of
a clean wound in the proliferative phase; however, the wound in this scenario
is an infected wound and would require a negative polarity (p. 277).
2. High-voltage pulsed current stimulates tissue healing via migration of cells
to the treatment area (p. 271). The positive electrode is most effective to
promote healing of a clean wound in the proliferative phase; however, the
wound in this scenario is an infected wound and would require a negative
polarity (p. 277).
3. Low-amplitude direct current is used for transdermal drug delivery via
iontophoresis (p. 274). Direct current can cause chemical effects that are
caustic and could damage tissue (p. 231). This would not be appropriate for
wound healing.
4. High-voltage pulsed current can stimulate tissue healing via galvanotaxis,
which results in migration of certain cells to the treatment area based on
, polarity (p. 271). The negative electrode is recommended when infection is
present (p. 277).
To perform postural drainage to the superior segment of the left lower lobe of
a patient's lungs, the patient should be in which of the following positions?
1. Prone position with pillows under the hips and the bed flat
2. Supine position with pillows under the knees and the bed flat
3. Right sidelying position with pillows behind the back and the foot of the bed
elevated
4. Right sidelying position with pillows under the abdomen and the head of
the bed elevated Right Ans - 1. Prone position with pillows under the hips
and the bed flat
WHEN THEY SAY SUPERIOR, THINK APICAL
A patient has a transfemoral prosthesis in which the knee friction is
inadequate. Which of the following gait deviations is the patient MOST likely
to exhibit?
1. Uneven step length
2. Abduction in stance phase
3. Terminal impact in late swing phase
4. Lateral trunk bending in stance phase Right Ans - 3. Terminal impact in
late swing will be observed if the friction is inadequate in a transfemoral
prosthetic knee.
1. Uneven step length is the result of an uncomfortable socket or insufficient
knee flexion.
2. Abduction in stance is the result of a long prosthesis, abducted hip joint,
inadequate lateral wall adduction, or a sharp or high medial wall.
3. Terminal impact in late swing will be observed if the friction is inadequate
in a transfemoral prosthetic knee.
4. Lateral trunk bending in stance is the result of a short prosthesis,
inadequate lateral wall adduction, or a sharp or high medial wall.
Which of the following exercises is MOST appropriate to strengthen the
abdominal muscles of a patient who has osteoporosis?
1. Trunk flexion in sitting position
2. Curl-ups from hooklying position
